**Contribution on Puzzlet #178**

** **Hello
again, Dave.

I found 9 numbers which solve this week's puzzlet:

00000 = 00000

02920 = 05550

09490 = 22422

13131 = 31513

13331 = 32023

26462 = 63536

26662 = 64046

30103 = 72627

30303 = 73137

I
did this in Excel using an algorithm to separate both the denary and
the octal numbers into digits, and then a logical operator to check for
palindromicity (now THERE'S a word you normally won't hear in daily
conversation.) Luckily, Excel has a function (DEC2OCT) which
performs
the conversion automatically. Also, I separated the problem into
two
sets: 0 to 32767, and then 32768 to 99999 to check for six-digit octal
palindromes, but alas there were none.

Thom,

Thanks for the input. You caught me out this week - I

didn't think of looking for integers beginning with zero!

I'm not sure if these are legal, in one sense, but I certainly

didn't exclude them.

Well done - I can see I'm going to have to devise a Puzzlet

which can't be solved using Excel! I didn't know it had a

Dec2Oct function.
