temporarily switch off `redSB`.
It would be as follow:
{{{
sage: from pGroupCohomology import CohomologyRing
sage: H = CohomologyRing(64,245)
sage: I = H.essential_ideal()
sage: singular.option()
//options: redSB redTail redThrough redefine loadLib usage prompt
sage: singular.option("noredSB")
sage: singular.option()
//options: redTail redThrough redefine loadLib usage prompt
sage: (I*I).NF('std(0)').interred()
a_4_8*a_6_8*a_1_0^3*a_1_3
sage: singular.option("redSB")
sage: (I*I).NF('std(0)').interred()
a_4_8*a_6_8*a_1_0^3*a_1_3,
a_4_8*a_6_8*c_8_16*a_1_0^3*a_1_3
}}}
Does the reviewer think that it is a valid work-around?
