I chose 2191*390*82589933 because my prime number generator only allowed 128 max digits.

My formula is 2n*3m*prime*large abundant numberĀ±1

I'm wondering whether it's still possible to find the next larger pair when both n and m are in the millions or larger with a mega-prime possibly the largest known Mersenne Prime.

I go from 20*3m to 2n*30, so I have a whole Arc rotation on a given orbit(fix # of numerical digits), doesn't have to be 128 digits, it can be 24 millions+ total.
