 Choosing the right m depends on the implementation.
Til and me used some adjustments/improvements for odd multipliers m > in our algorithm the good multipliers are not only even, best multipliers are odd.
the numbers from nesio model : 6,12,36,60,120,360,720,1680,... do not appear in the list of good multipliers for this tuned algorithm in the top
 the number of divisors is the product of the exponents + 1 of its prime factors
If the exponents are all 1 then this is just 2^(number of prime factors of m). Having a factor with an exponent greater then one reduces the number of divisors. > it looks like a good measure for good multipliers. But our best multiplier 315 = 3^2 * 5 * 7 has an exponent 2.
When finding the best multipliers for numbers starting at 2^54 (and only factoring numbers with factors above n^1/3) I get a complete different list then when factoring numbers starting at 2^55.
