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

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

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