- bel">•
Two families of first integrals of van Diejen's rational BC(n) system are considered.
- bel">•
Equivalence of these two complete sets of Poisson commuting Hamiltonians is proved.
- bel">•
Van Diejen's Hamiltonians depend linearly on those generated by Pusztai's Lax matrix.
- bel">•
The explicit formula of this invertible linear relation is found.
