Presentation

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

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

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