Presentation

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

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

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