Presentation

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

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

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