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

A minimal faithful permutation representation — 5 generators on 28 points:

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