Presentation

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

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

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