comment Is The Clique Algorithm by Ashay Dharwadker correct?
Here is a counterexample for his other P=NP attempt (Hamiltonian cycle one: dharwadker.org/hamilton ): pastebin.com/jqZ6d3dm (use as graph.txt for his app). Hamiltonian cycle exists for this graph (it is $1,2,3,\dots,13,1$) but his algorithm finds only a path with 12 out of 13 vertices.

comment How prove this matrix inequality $\det\left(6(A^3+B^3+C^3)+I_{n}\right)\ge 5^n\det(A^2+B^2+C^2)$?
$A^{2n+1}=-A$ rarely holds for $A\geq 0$. In fact it holds only for $A=0$, so given the requirement $A+B+C=1$ it can't hold for all 3 matrices. So your example doesn't cover any valid case.
