Seven Shirt Settlement (Posted on 2022-05-05)

Seven shirts are arranged side by side in a straight line. The 7 shirts have these colors:
purple, red, blue, yellow, brown, orange, and green, although not necessarily in that order.

The following is known about these seven shirts:

The two colors that start with "b" are not next to each other.
The Yellow shirt is not next to the Orange shirt.
The Red shirt is directly between two of the colors each having the second letter as "r".
The Blue shirt is next to the Orange shirt.
The Orange shirt is second to the left.
Either the red, purple, or both are somewhere to the right of the Brown shirt
There is precisely 1 shirt between the Green shirt and the Orange shirt.
The Yellow shirt is next to the Green shirt.

Determine the precise order of these seven shirts from the clues provided in the above-mentioned statements.

Too many clues (analytical spoiler)

| Comment 2 of 3 |

From Clue 5, Orange is in Position 2

Then, From Clue 7, Green is in position 4

Then, From Clues 2 and 8, Yellow is in Position 5

Then, From Clue 3, Red is in Position 3

Then, From Clue 4, Blue is in Position 1

Then, from Clue 6, Brown is in Position 6 and Purple in Position 7

This agrees with Charlie's computer solution.

Note that Clue 1 was not needed.

Also, Clue 6 could have been simplified to just say that Brown was not the rightmost short.
