Presentation

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

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

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