During past years, author studied different types of "selfie numbers", with extra operations as, factorial, square-root, Fibonacci sequence values, etc. This paper brings "selfie numbers" in terms of "binomial coefficients". This has been done in digit's order, reverse order of digits and in both ways. The results are limited to five digits. See below some examples: … Continue reading Selfie Numbers and Binomial Coefficients

# Magic Square Type Extended Rows Palprimes of Order 5×5, 7×7 and 9×9

This work brings magic square type palindromic primes (palprimes) numbers of order axa, in such a way that rows, columns and principal diagonals are all palprimes along with extended row of rows. This kind of palprimes are named as "magic square type palprimes" or "palprime distributions" of order axa. This work is limited to palprime distributions of … Continue reading Magic Square Type Extended Rows Palprimes of Order 5×5, 7×7 and 9×9
