The list has 52655 which almost certainly is 852655 sans the initial 8. I also read that he works at Intel and also wrote a paper together with Neil Sloane on some other sequence [1]. But no amount of access to hardware and no more or less straight forward optimization of the code given will bring you anywhere near calculating 10²³⁰ terms. You would need an algorithm that could essentially compute somewhere between 10¹⁰⁰ and 10²⁰⁰ terms per clock cycle to stand any chance. The closest thing I am aware of would by something like hashlife [2], an algorithm to speed up game of life simulations…
