Base-dependent integer sequences
In number theory, an extravagant number (also known as a wasteful number) is a natural number in a given number base that has fewer digits than the number of digits in its prime factorization in the given number base (including exponents). For example, in base 10, 4 = 2², 6 = 2×3, 8 = 2³, and 9 = 3² are extravagant numbers (sequence in the OEIS). There are infinitely many extravagant numbers, no matter what base is used. (Wikipedia).
