EDIT: This question appears to be getting repeatedly misunderstood, as captured by DoubleAA's comment. MTL has helped me explain.
You're NOT looking for the minimum number of people for Judaism to exist. You're looking for the smallest number of people who can fulfill all mitzvos (given the context of a fully functioning halachic Jewish society)
In a nutshell, the Arizal says we are reincarnated so that every Jew gets a chance to experience all 613 mitzvot as a chiyuv in at least once. My question is, how many reincarnations would that take, minimum, and which category of Jew would each of those incarnations be?
Who's on the Mitzva Dream Team, the team that could single-handedly win the 613 World Cup?
Here's the original question, with clarifications and rules:
A classic Mi Yodeya question, perhaps a little more light-hearted in the spirit of Purim round the corner (not PTIJ)-
What's the minimum number of Jews we need so that between them they are personally actually mechuyav (halachically obligated) in all 613 Mitzvot, in their lifetime? If we just have a Yisrael, he is not mechuyav in the Cohanic mitzvot, for example. If we just have a men, nobody is mechuyav in the mitzvot of women etc.
So based on the above, we need at least an Israel, a Cohen and a woman. We'd also need a King, but we can be clever and combine categories; if a King is mechuyav in all mitzvot of an Israel, then we don't also need an Israel. We are going for the minimum number.
Maybe a Cohen Gadol can cover everything a Cohen does? Should there be a separate mamzer?
Let's assume the Temple is still standing, the tribes are in the land etc. etc.
Circumstances can change over life, so I mean across a whole life time. I.e. A person can be eligible for mitzvot of being a child and a parent in a single life, so we don't need to have both a child and a parent in our little mitzva dream team. An eved can be freed etc.
With regards to the negative commandments, I welcome people dealing with this in their own way, or defaulting to saying that they should have a valid opportunity to break them. One of them for example should be a male with a sister, to keep the commandment of not lying with one's sister.
People required to assist the dream team to keep those mitzvot do not count as part of the dream team. In the above example, the sister does not need to be counted as one of the team, but the brother who refrains from lying with her does. If (hypothetically) women have a distinct mitzva to not lay with their brother, then we'd need a woman in the team with a brother (and we can utilize the above sister if we are being very clever)
To make it simpler, if a single Mitzva has multiple angles, "don't lay with your brother or sister", but it's just one mitzva, then fulfilling it from one angle is enough.
Has anyone calculated this ever? If not it might be something someone here with a great knowledge of the mitzvot can calculate for us. Sounds fun!
Background to question: I ask this question based on thinking about Shaar Gilgulim Ch. 16 that all mitzvot are covered over gilgulim. I imagine this is rather poetic, or more complicated than that, as not everyone was once a King I imagine! Still, one wonders if we can achieve a Mitzva Dream Team of just 4 people according to the Asarah Perakim L'Ramchal 10:3, which states most Jews are only reincarnated up to 4 times based on Amos 1:3
To make it as clear as possible then, this is a thought experiment:
We are trying to prove what is the minimum number of reincarnations everyone would have to go through in order to personally experience all 613 mitzvot on the level of chiyuv, by assuming different Jewish roles in each reincarnation, and take as given that Hashem will help and ensure they have all the setting and opportunities they need to do so.
