      Dear colleagues:

      I have found two identities:

      1) Product[k^Floor[n/k],{k,1,n}]=
      Product[Floor[n/k]!,{k,1,n}]


      2)(Product[(i^j)*(j^i),{i,1,n},{j,1,n}]/Product[i!*j!,{i,1,n},{j,1,n}])^(1/n)=
      Product[C(n,i),{i,0,n}]

      OEIS A001142

      This identities are known?

      Sincerely

      Sebastian Martin Ruiz
