Irish bouzouki even 27 inches (66 to 68 cm). These longer-scaled instruments are generally acknowledged to possess greater volume, sustain, and tonal richness but some players find the stretches involved in fingering too difficult and so prefer shorter scale lengths. Irish bouzouki The Irish bouzouki () is an adaptation of the Greek bouzouki (Greek: μπουζούκι). Johnny Moynihan is credited with bringing the first "tetrachordo" (4 courses of strings) Greek bouzouki to Ireland and retuning it to G-D-A-D (in intervals he first used on the mandolin). In the mid-1960s, Moynihan established a presence for the instrument in Irish music with the folk trio
Shannon capacity of a graph eight neighbors, the eight strings that it can be confused with. A subset of length-two strings forms a code with no possible confusion if and only if it corresponds to an independent set of this graph. The set of code words {"11", "23", "35", "54", "42"} forms one of these independent sets, of maximum size. If "G" is a graph representing the signals and confusable pairs of a channel, then the graph representing the length-two codewords and their confusable pairs is "G" ⊠ "G", where the symbol "⊠" represents the strong product of graphs. This is a graph that has
