An alphome consists of the letters of a word placed in alphabetical order, AEGINRST, AELRST and others have been the subject of intensive work over many years, the object being that make as many words as possible using each letter just once per word. Although I agree that these strings were the most common (or threreabouts) of their length, I note that the lists produced were more than an order of magnitude larger than the number of occurrences even in the largest dictionary I have seen.
