The description above is the correct layout of the undercarriage on a
Trident. The undercarriage is also fairly unique in that to stow the 4
wheels on a single main gear axle, the leg shortens and rotates
through 90deg. so that the wheels occupy the minimum space possible.
Of course the extra complexity added weight to the design - hence this
approach hasn't been used since on civil aircraft.
