OEIS Sequences

Consider a number of k digits n = d_k*10^k-1 + d_k-1*10^k-2 + … + d₂*10 + d₁. Sequence lists the numbers n such that σ(n) - n = ∑_i=1..k-1{σ(∑_j=1..i{d_j*10^j-1})} (see example below). A240895

Sp = reversal of some square s where s = x² for x = 1,2,.. (ignoring leading zeros). Sp is in the sequence if it is semiprime. A242097

Primes p from A031924 such that A052180(primepi(p)) = 7. A52231
