 Aug 24 comment Finding a function such that $(n-2)/2 + f(n-1) \leq f(n)$ @abiessu Yes that's what I mean. I'll correct the question. Though if I understand your last comment it is fact not possible to obtain such f?

Unless you are happy with a proof involving Sage math :) Jul 15 accepted A construction of a Hadamard matrix Jul 13 comment A construction of a Hadamard matrix @darijgrinberg Thank you - that helped. I'd be glad to accept this as an answer in case you want to copy paste the comments as an answer.

May 30 comment number of cycles in arbitrary graph Hint. If you add an edge to a spanning tree you obtain a cycle. Adding distinct edges gives you distinct cycles.
