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