Actually, this has come up before. When you enter an expression in the search box, it is parsed to come up with a value to query. Since the two expressions crunch to different values, the DB starts from two different IDs. If you feed the factors from the first result to the second result, it will figure out that the second one is FF also......

It would be nice if the engine was able to figure that out automatically. If I use it for factoring, I do not want to care about relationship of the input number to other numbers in the database, I just want to pull up from the database as many factors as possible.

Use the factor tables page displaying only one number in text form.

The aliquot sequence for 174888 seems to be broken... it appears that sigma was computed incorrectly at term 143.

This is a totally "new" branch of 174888, which branch never went over 100 digits, it is a "new" acquisition, maybe a mistake happened on the server in the last days, and the DB elves just worked it on to 75 digits. If it should be older, then it should be worked higher. As additional proof, filling 8171995960632149250568 as a start for a sequence, it goes to 116 digits, with 2^3*3*5 (that is "my" driver! :P) Last fiddled with by LaurV on 20120214 at 03:53

The problem is this line: Code:
142 . 8734000210977209181752 = 2^3 * 37 * 193 * 152884753728070459 Code:
152884753728070459 = 207715517 x 736029527 Last fiddled with by schickel on 20120214 at 07:33 Reason: Changed verb/subject agreement slightly.

The 3000 limit is for a nonlogged in users and it appears to be tracked by IP. I wonder how widely spread the users of the DB are.....

@Syd, can you force the DB to reclaculate 174888? Maybe it can be reconstructed....
