Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(2,4)(5,6)(7,8)(9,10)(11,12)(13,14,17,20)(15,18,22,26)(16,19,23,27)(21,25,24,28);(1,2)(3,4)(9,11,12,10)(15,21)(16,23)(18,25)(19,27)(22,24)(26,28);(10,11)(13,15,17,22)(14,18,20,26)(16,24,23,21)(19,28,27,25);(2,4)(6,8)(10,11)
