AB -> ABBA -> ABBABAAB ... This allowed me to get a computer to achieve the algorithm in many ways, but it also raised some questions. Question 1: Can I repeat this forever and have it properly generate the algorithm? The algorithm is normally created by taking AB, then inverting each 2-state 'digit' and sticking it on the end (ABBA).
$A^2=AB+BA$. Prove that $\\det(AB-BA)=0$

How to calculate total combinations for AABB and ABBB sets?
10 May 2025 at 1:39pm
Although both belong to a much broad combination of N=2 and n=4 (AAAA, ABBA, BBBB...), where order matters and repetition is allowed, both can be rearranged in different ways: First one: AABB, BBAA, ABAB, BABA, ABBA, BAAB (6 possible combinations) Second one: ABBB, BABB, BBAB, BBBA (4 possible combinations)
