Presentation

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

A minimal faithful permutation representation — 4 generators on 20 points:

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