Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:

2^8|a^2=h,b^2=ef,c^2=e,d^2=g,b^a=be,c^a=cf,c^b=cg
