Amiram Eldar, Table of n, a(n) for n = 1..10000
FORMULA
a(A347771(n)) = 0.
EXAMPLE
a(1) = 2 since there are two solutions to uphi(x) = 1: 1 and 2, and 2 is the larger of them.
a(6) = 14 since there are three solutions to uphi(x) = 6: 7, 12 and 14, and 14 is the largest of them.
MATHEMATICA
a[n_] := If[(inv = invUPhi[n]) == {}, 0, Max[inv]]; Array[a, 100] (* using the function invUPhi from A361966 *)
