Deletion of Seventh power

Comment: Multiple nontrivial mathematical publications are about this subject, to the extent that they have "seventh powers" in their actual titles. I just added several as references to the article. Therefore, this subject passes  (the subject of multiple nontrivial works) and  (a sequence of numbers with multiple nontrivial properties). In addition, Google scholar indicates that there appear to be many seventh-power laws in physics
