I think the best way to approach this problem is to first try to solve
it assuming there are only two robbers rather than 20. Then once you
have that figured out, try it for three, then four, and so on. Keep in
mind that 50% support is enough for a proposed distribution to pass, you
don't need a strict majority.

Exactly. I arrived at the solution the same way. Note that there is another
assumption needed--that the selection of a proposer is by lot at each new
stage. If the ordering of proposers is known in advance, a different
solution results.
A further assumption is that a certainty gain of 1/n of the total sum is
preferred to a 1/n probability of gaining the entire sum and a (1-1/n)
probability of gaining nothing..

Yes, the cypherpunk robbers are ordered by alphabet.
