# Sunday Times Teaser 2959 – The Magnificent Seven

### by Graham Smithers

After a day’s filming, a group of those involved in the film’s production went for a gallop.

They split into threes, with a samurai leading each grouping.

The seven samurai were:

BRONSON,  BRYNNER,  BUCHHOLZ,  COBURN,  DEXTER,  MCQUEEN and VAUGHN

The others involved in the gallop were:

ALANIZ,  ALONZO,  AVERY,  BISSELL,  BRAVO,  DE HOYOS,  HERN,
LUCERO,  NAVARRO,  RUSKIN,  RUSSELL,  SUAREZ,  VACIO and WALLACH

For each grouping, any two names from the three had exactly 2 letters in common (eg, BRYNNER and BRAVO have B and R in common).

If I told you who accompanied BRONSON, you should be able to tell me who accompanied (a) MCQUEEN and (b) DEXTER

This solution uses the partition_unique utility described here

I’m struggling with the white solution as it appears you can substitute Russell with Ruskin.
Where have I gone wrong?

Hi Bill, I suggest that you ask your question on this site as you re more likely to get help there. In any event, it will be impossible to say what you are doing wrong until you set out your solution in detail. By the way, it isn’t sufficient to show that you have groups for Bronson, Dexter and McQueen that work – you then have to show that the other four groups are also possible using those left.

If Bronson = Brian’s white text value, Brynner must be Navarro + Ruskin
