• Self-power numbers (or SPN's): numbers n with property that for each single digit d of n, we can also see the decimal expansion of the d-th power of some number as a substring of n and also n contains no 0's or 1's.at n=2A134698
• Primitive self-power numbers (or SPN's): terms in A134698 which cannot be obtained by taking an earlier term M (say) of A134698 and prefixing, inserting or suffixing a digit of M.at n=1A134949
• a(n) = n*(n-1)*(n+1)*(3*n-2)/12.at n=31A153978
• Expansion of e.g.f. log(1 - log( sqrt(1-2*x) )).at n=8A363115
