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

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

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