I was reviewing some competitive programming concepts in preparation for today's Div 4 Codeforces contest and I came across this sequence while doing a problem on recurrence relations (matrix exponentiation): https://oeis.org/A322054
My math senses were strong enough to spot a logical flaw (just one word!) in one of the examples written by Neil Sloane himself, the founder of the Online Encyclopedia of Integer Sequences, that remained undetected for EIGHT YEARS! (you can see in the image that the OEIS was indeed founded by Sloane and that he authored the sequence)
This led me to create an OEIS account and promptly fix the error :))
