# The circle of three

I'm the first, but also second

I'm rather odd, but also not

I am the circle of three

What am I?

• For those who liked this puzzle: The circle of two. Commented Jan 6, 2016 at 18:21

You are:

2

I'm the first, but also second

The first prime, but also the second (depending on convention: 1 used to be regarded as prime).

I'm rather odd, but also not

2 is the oddest prime (it is even).

The circle of three

???

• You are correct! For solving the third clue, here is a hint: Think of pi instead of the circle. Also, in the first sentence is another clue. First is a synonym of prime, as in e.g. prime minister. And it is the second natural number. Commented Jan 6, 2016 at 18:09
• $\Bbb Z_2$ is only {0,1}. {0, 1, 2} is $\Bbb Z_3$ Commented Jan 6, 2016 at 21:42
• The third clue translates to $\pi(3)$, where $\pi(n)$ is the prime-counting function. Commented Jan 7, 2016 at 22:56
• @IvanBarreto That is where I wanted my clue to point to. Commented Jan 25, 2016 at 19:30

You are the

Second hand in a clock

Explanation Follows

I'm the first, but also second

Second hand is the fastest and to reach the 12 hour mark first. But its calles Second.

I'm rather odd, but also not

Some time the second hand points to an odd number but in the next instant it will be an even number

I am the circle of three

The rotation of second hand manages second, minutes (one complete rotation of second hand) and hours (60 complete rotations of second hand). The numbers/points in circular form in a clock represents seconds, minutes and hours.

• Very close, and good explanation, but not where I was looking for. Commented Jan 6, 2016 at 10:06
• The last clue fits more to the number marks in the clock. May be that's what your intended answer is. :) Commented Jan 6, 2016 at 10:07
• No that is also not the correct answer. In fact, your original answer is closer. Commented Jan 6, 2016 at 10:09

You are:

a clock

I'm the first, but also second

the first to show the time and the seconds in the time

I'm rather odd, but also not

the hour, minute and second can be odd numbers and also can be not odd i.e. even

The circle of three

a clock is a circle with three hands

• No, you removed the wrong part from the other answer. Commented Jan 6, 2016 at 13:46

You are:
