Orfi %J International Journal of Group Theory %D 2012 %I University of Isfahan %X It is shown that there are exactly seventy-eight 3-generator 2-groups of order $2^{11}$ with trivial Schur multiplier. We then give 3-generator, 3-relation presentations for forty-eight of them proving that these groups have deficiency zero. %K Schur multiplier %K presentation %K deficiency zero %K finite $p$-group %K lower exponent-$p$ central series %U http://www.theoryofgroups.ir/?_action=showPDF&article=470&_ob=fcd7ddcb5b52b3c1b3764203d5e9bab6&fileName=full_text.pdf
