 OFFSET 1,2 COMMENTS The partition with Heinz number n is given by the prime signature of A025487(a(n)). LINKS Table of n, a(n) for n=1..66. Index entries for sequences that are permutations of the positive integers FORMULA a(A181820(n)) = A181820(a(n)) = n. EXAMPLE The partition with Heinz number 18 = prime(1)^1*prime(2)^2 is (1,2,2), and prime(1)^2*prime(2)^2*prime(3)^1 = 180 = A025487(20), so a(18) = 20. CROSSREFS Cf. A025487, A181820, A361809 (fixed points). Sequence in context: A132430 A049537 A039171 * A320144 A039270 A039208 Adjacent sequences: A361804 A361806 A361807 * A361809 A361810 A361811 KEYWORD nonn AUTHOR Pontus von Brömssen, Mar 25 2023 STATUS approved
