Sequences that pass recursion test, but ...

[Tanya Khovanova]

The complement sequence is A088472 which starts 1, 2, 3, 4, 5, 6, 7, 8, 9, 100, 110, 112...
All the sequences A088472-A088481 could have the same correction to their definition.

Martin Fuller

PS Has something happened to sequences A087637 and A087639? They are referenced by A087097 "Dismal
primes" but appear to be unrelated.
