# Triperfect number

A triperfect number is a positive integer n such that the sum of its divisors is equal to 3 times n.

The sequence of triperfect numbers begins:

120,672,523776,459818240,1476304896,51001180160

These are all the triperfect numbers that are currently known.

Examples: 120 is triperfect:

σ(120)=360=3×120

672 is triperfect:

σ(672)=2016=3×672

523776 is triperfect:

σ(523776)=1571328=3×523776

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
• Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Oohhhhh!!! This is soo cool!!! Thanks for this info!!!
P.S. to send the link in a concise manner, you can [Write link text] (enter link here).............Like This.......... Just, there should be no space between the square and the curve bracket......
