Number sequences that aren't (mathematical).

I found it by googling and because of that I did not wish to post. However...
it is also the Date of the first Sunday of each month in 1991, 2002, 2013, 2019, 2030, 2041, 2047, etc, Intervals are 11,6,6,11,11,6...

For this reason I consider the sequence mathematical.

This one is a finite set, but I will not post all elements, just the first few and the last.

3, 3, 1, 2, 4, 3, 2^*, 3, 1, 1,......, 3
*Some may contend that this element should be 3

How many terms are in the sequence?

It would seem there is nothing that google doesn't know. I dread the day when it becomes self aware.

I choose not to reveal that. It may make it too easy.

[edit]I will reveal that the sequence is more than 20 and less than 40[\edit]

Here is an example:

1, 5, 3, 6, 2, 4

This is a cylinder firing order commonly used in 6 cylinder inline engines.

It may also be viewed as the sequence of numbers of pips on the faces of a cubical die. The first 3 numbers are on the faces that meet at one corner, and the second three are the numbers on the faces opposite the first 3. (The number of pips on opposite faces always add to 7).

An easy one (not all elements of the sequence)

0 0 1 2 ...14 27 ...

Sorry, the order was switched in the original post. This is the correct order.
0 0 1 2 ...27 14 ...

Please try to convince me that it is not.

I genuinely do not know whether Google is self-aware. I suspect not but can't demonstrate it to my own satisfaction.

Maybe it is. When it gets to the toddler stage and starts throwing paddies then we will know.
