My algorithm mimics 2^P1 with the golden ratio
I was messing around with the golden ratio and some other numbers at
https://keisan.casio.com/calculator and I produced this algorithm. The input is in red. It will find mersenne numbers 5.2/3.999999999999999^1.618033988749(27+(sqrt(2^21))^3)+2^21 Last fiddled with by ONeil on 20201104 at 20:39

Code:
5.2/4^((Sqrt[5]+1)/2*(27+(Sqrt[2^21])^3))+2^21 Trivial solution: the exponent of 4 is large: ((sqrt(5)+1)/2*(27+(sqrt(2^21))^3))=52.09, so the 5.2/4^exponent is very small, the expression's value will be close to 2^21=3. Last fiddled with by R. Gerbicz on 20180417 at 07:18

c + 2^n  1, where c is ~= 10^31 So it might as well be: 0 + 2^n  1, which is just 2^n  1 ETA: It isn't an "algo", it is a formula. Last fiddled with by retina on 20180417 at 07:30

Still its interesting because you can edit to get other outputs. Retina what is the difference between an algorithm and a formula?

Not really, it is just 2^n1, not interesting at all unless you consider the trailing 10^31 (which your calculator hid from you). You are basically saying that 2^n1 equals 2^n1.
