EXAMPLE
A025487(2) = 2, prime signature {1}. There are a maximum of 2 consecutive integers with that prime signature: 2 and 3.
A025487(4) = 6, prime signature {1,1}. There are a maximum of 3 consecutive integers with that prime signature (e.g., 33, 34 and 35).
A025487(6) = 12, prime signature {1,2}. There are a maximum of 5 consecutive integers with that prime signature (e.g., 10093613546512321, 10093613546512322, 10093613546512323, 10093613546512324, and 10093613546512325). Compare A141621.
A025487(13) = 60, prime signature {1,1,2}. There are a maximum of 7 possible consecutive integers, between two multiples of 8, with that prime signature; the smallest such run starts at 932537185321. - Bernard Schott, Feb 16 2021
