We define a group theoretical invariant, denoted by s G , as a solution of a certain set covering problem and show that it is closely related to chl(G), the cohomology length of a p-group G. By studying s G we improve the known upper bounds for the cohomology length of a p-group and determine chl(G)
## Abstract The effect of the stamp stretching during microβcontact printing (ΞΌCP) onto the corresponding printed poly(3βhexylthiophene) (P3HT) layer has been analysed both from morphological (AFM) and structural (XRD) points of view. Results show an orienting effect of the stretching towards the P
