On the Existence of Frames of Some Extremal Odd Unimodular Lattices and Self-Dual Zk-Codes
Masaaki Harada, Tsuyoshi Miezaki
For some extremal (optimal) odd unimodular lattices L in dimensions n=12,16,20,32,36,40 and 44, we determine all positive integers k such that L contains a k-frame. This result yie…
