During the exploration of the neighborhoods of generalized symmetries of DLS of order 10 in the third parastrophic slice another promising area (3,15) was found, in which, upon a brief examination, several 2-CF lines-3 and 3-CF cycle-4 was found (both are rare combinatorial structures). Currently prepared 400k WU's for a more detailed study of this neighborhood. They will be added to the project immediately after the elimination of minor problems arising in connection with the transfer of the project to a new server. It is very likely that the arrangement of interesting regions as a whole repeats a similar arrangement in the first parastrophic slice, although the "physical meaning" of these generalized symmetries is completely different.
