Decomposition of Oddish numbers
Oddish numbers (prime to 10 and 10's digit is odd).
Decomposition of A045844
a(n+1) = a(n) + largest digit of a(n); a(0) = 1.
Decomposition of A045920
Numbers n such that factorizations of n and n+1 have same number of primes (including multiplicities).
Decomposition of A045939
Numbers n such that factorizations of n through n+2 have the same number of primes (including multiplicities).
Decomposition of A045941
Numbers n such that the factorizations of n through n+4 have the same number of primes (including multiplicities).
Decomposition of A045942
Numbers n such that the factorizations of n through n+5 have the same number of primes (including multiplicities).
Decomposition of A046025
Numbers n such that 6n+1, 12n+1 and 18n+1 are all primes.
Decomposition of A046034
Numbers whose digits are primes.
Decomposition of 6-almost primes
Numbers that are divisible by exactly 6 primes with multiplicity.
Decomposition of 7-almost primes
Numbers that are divisible by exactly 7 primes counting multiplicity.
