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