Unclear, needs rewording
Let call pisano, the Pisano period (pisano(2) = 3).
Confused me anyway. I grok π(2)==3 (as one of many) from the wikipedia page, but not entirely sure what the wordage should be here. How about
Let pisano(n) denote the Pisano period (e.g. pisano(2) is 3).
- I re-introduced coprime and mentioned prime factorisation as they are mentioned on the wp page and seem to be an important part of the calculation. --Paddy3118 (talk) 17:32, 4 March 2020 (UTC)
