Presentation

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

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

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