Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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