Presentation

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

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

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