Which was the configuration to BICh-25 ?

[zhuravlik]

In "Soviet X-planes" is stated:"In June 1948 the BICh-24 was followed by the BICh-25, a project for a jet fighter with variable-sweep wings with outboard pivots, uncannily like the American TFX projects of more than ten years later."

Does anyone have some additional data about this BICh-25?
Seems like another chapter of "Who copied who" psycodrama :

Best regards,
