It is shown that NP equals the closure of \(\lambda xyz.z=x^*y\) \((^*\) denotes concatenation of numbers in m-adic notation) under \(\bigvee,\&,(\forall x)_{Py},(\exists x)_{Py},(\exists x)_{\leq y}\), explicit transformation and substitution of \(\lambda xy.x^{| y|}\) for a variable, where \(| |\) denotes m-adic length.
