I like this semiprime with the interesting doubledouble format nearby the right end: 13,898,772,659,372,959

Ben Delo's wavefront is around M107.1M and the UncWilly drought still persist with less than a full year to go to become the longest gap of discovering a new Mersenne Prime after the previous one. Even M116M and M117M seems to be too long to work on for DrKirkby despite the request from Zhangrc to ask him to stay and just play more casually. Base 5 dozens with a dozenal superbase is still somewhat different than Base sixty with a decimal superbase. Since it's probably not possible to use base sixteen to figure out how the residue values of a PRP tested exponent relates to the location of a hidden Mersenne Prime. It's okay to try on base 1 dozen 4. At least this list isn't too long for me to finish, but still too many to allow only 5 guesses from Mathwiz. Quote:
I'm assuming if the next hidden Mersenne Prime really ends with Ɛ, then it has the higher chance to be 4Ɛ for the final 2 digits dozenally. Quote:
If I have AMD Threadripper 5970X with Nvidia Geforce 3090 Super, I should be able to finish 1 M168,***,*23 exponent every 4~5 days. The M168,*8*,*23 list will only last several months. The only reality that will trouble me is the supply shortage that'll prevent me from purchasing the PC I want, thus unable to prove myself. Last fiddled with by tuckerkao on 20211018 at 20:39

This is gobbledygook^{3}. Whether a number is one less than a highly composite number does not depend on what base you express it in. The term "dozenal enders" implies base twelve. A 2digit ending in base twelve would be a congruence class modulo 144. Assuming "base 5 dozens" means "base sixty" a given congruence class mod 144 would correspond to 25 possible 2digit endings in base sixty. I have no idea what you mean by "as a regular number," but the phrase uses the singular "number" in referring to the plural "dozenal enders" so is ungrammatical. Assuming your excessively obscure notation "dozenal 4Ɛ enders" means "numbers congruent to 59 modulo 144", adding 1 to such a number gives 12 times a number congruent to 5 (mod 12). Base sixty is base sixty. Also, one radix or base that is a multiple of a given base is a "superbase" of the given base. You have it the wrong way around.
