Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 20 points:

(6,8)(9,10,12,11)(13,14,16,15)(17,18,19,20);(5,6)(7,8)(17,18)(19,20);(6,8)(9,10)(11,12)(13,14)(15,16);(2,4)(9,10,12,11)(14,15)(17,18)(19,20);(2,4)(10,11)(13,14,16,15)(17,18)(19,20);(1,2)(3,4)(5,6)(7,8)(9,11,12,10)(13,15,16,14)
