Presentation

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