COMMENT

A graph shows this is chaotic. The frequencies of the frequencies are a step down type function: 10,12,11,10,10,10,10,10,10,9,9,8,8,8,8,7,7,6,6,6,6,6,4,4,4,4,4,3,3,3,2,2,2,1,1 unlike A004001 in which the frequencies of the frequencies are powers of 2 stepping down.

MATHEMATICA

Conway[n_Integer?Positive] := Conway[n] =Conway[Conway[Conway[n-1]]] + Conway[n - Conway[n-1]] Conway[1] = Conway[2] = 1 digits=3000 a=Table[Conway[n], {n, 1, digits}]; mx=Max[a] c=Table[Count[a, m-1, m], {m, 1, mx}] d=Delete[c, 1]
