Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

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