Comments

Sequence differs from A160402; a(n) = A160402(n) for first 3098 terms, a(3099) = 203457869.

Subsequence of A243362. Supersequence of A160402 and A243363.

Primes p such that A243361(p) = 123456789.

Conjecture: sequence is infinite.

Examples

			Prime 200000000003456789 is in sequence because A176558(200000000003456789) = 2000000000034567891; each digit 1 - 9 appears exactly once.
