the remodd numbers do not seem especially rare: I get
43, 47, 73, 87, 223, 227, 253, 267, 283, 289, 337, 343, 349, 367, 379, 397,
433, 439, 463, 467, 469, 477, 489, 493, 523, 553, 583, 643, 647, 649, 669,
673, 677, 687, 689, 733, 747, 787, 799, 823, 827, 829, 849, 853, 869, 883,
887, 889, 943, 997,...
- does anyone agree? Both should be added to the OEIS, I think.
Best regards
