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