Distinct k for which A001414(k) = m relates to the number of prime partitions of m and are listed in row m of A064364. For example, k in {7, 10, 12} have A001414(k) = 7. Once these k have appeared in A277272, there is no other way to obtain m = 7 in this sequence. Hence m = 7 is exhausted in this sequence. %C A349543 Terms are greater than 1. %H A349543 Michael De Vlieger, <a href="/A349543/b349543.txt">Table of n, a(n) for n = 1..10001</a> %H A349543 Michael De Vlieger, <a href="/A349543/a349543.png">Log log scatterplot of a(n)</a> for n=1..2^17, accentuating n <= 2^10 with small points, and n <= 32 with medium points for better visibility. %t A349543 m = 2, n = 1, s[_] = c[_] = 0; s[2] = 2; c[2]++; {2}~Join~Reap[Do[k = 3; While[Nand[GCD[If[s[k] == 0, Set[s[k], Total@ Flatten[ConstantArray[#1, #2] & @@@ FactorInteger[k]]], s[k]], s[m]] > 1, c[k] == 0], k++]; Set[n, k]; Sow[s[k]]; c[n]++; m = n, 70]][[-1, -1]] %Y A349543 Cf.
