We say that a totally unimodular matrix is k-totally unimodular (k-TU), if every matrix obtained from it by setting to zero a subset of at most k entries is still totally unimodular. We present the following results. (i) A matrix is restricted unimodular if and only if it is 3-TU, (ii) for a 2-TU m

## Abstract The methods developed for eigensolution of matrices with special patterns (__Commun. Numer. Methods Engng__ 2003; **19**: 125; 2004; **20**: 133) is extended to another canonical form defined as the __symmetry of Form IV__. Efficient methods are presented for evaluating the eigenvalues
