Presentation

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

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

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