Submitted on the same day as A144565 and by the same author are
A144566 to A144569.
Numbers with more prime factors (multiples counted) than the values of
their largest prime factor. 72 and 81 are missing.
These are, in order and excluding the first term, the primes in
A074320. However, a 5 is missing after the second 19.
48, 63, 99 are missing. 158, 189 shouldn't be there.
The second 56 should be 58. 72 shouldn't be there.
