COMMENT

Limiting ratio is:34.00000019808332

This sequence represents the Matrix Markov of the 36by36 game matrix

of a six person game with pyramidal or Hierarchical structure.

It appear to be the lowest possible such game with multiple values.

Not effort was made to use the whole 36by36 matrix made up of six 6by6

matrices of three types.

The idea is that ancient societies had a structure of poor to rich

in a relative pyramid. Here the lowest level get the smallest payoffs, the intermediate gets more and the leader gets the highest payoff.

FORMULA

a(n) = Expansion(1/(1 - 40 x + 218 x^2 - 492 x^3 + 553 x^4 - 308 x^5 + 54 x^6 + 248 x^7 - 984 x^8 + 1604 x^9 - 1178 x^10 + 324 x^11 + 55 x^12 - 592 x^13 + 1644 x^14 - 1732 x^15 + 625 x^16 - 100 x^18 + 688 x^19 - 1208 x^20 + 620 x^21 + 95 x^24 - 392 x^25 + 330 x^26 - 46 x^30 + 88 x^31 + 9 x^36))

MATHEMATICA

f[x_] = (-1 - x^5 + x^6)^4*(-1 - 2*x^5 + x^6)*(-9 - 34x^5 + x^6); g[x_] = Expand[x^36*f[1/x]]; a = Table[ SeriesCoefficient[Series[1/g[x], {x, 0, 30}], n], {n, 0, 30}]
