Presentation

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

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

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