(/showthread.php?tid=908) [rule 30] Is it possible to easily rewrite rule 30 in terms of modular arithmetic ? - tommy1729 - 07/24/2014 Is it possible to easily rewrite rule 30 in terms of modular arithmetic ? I Always want to rewrite cellular automatons/tag systems in terms of modular arithmetic. But it seems hard. So take rule 30. we have imput A , B , C and output D. all values are either 0 or 1. Can we easily find F(A,B,C) = D mod 2 or some similar modular arithmetic to do rule 30 ? I assume to take F as an integer polynomial. I consider replacing values 0,1 with 2,3 and doing F*(A,B,C) = D mod 5. But Im still puzzled. And kinda embarressed to ask. There is, or might be , a slight connection to tetration. But dont ask yet, its complicated. regards tommy1729
