"**Instructions:**  
Analyze the given molecule represented as an image to determine the total number of ketone functional groups present in the molecule.

- Atom indices are labeled directly adjacent to each atom in the image.
- Identify ketone group, defined as a carbonyl (C=O) group, where the carbon atom is directly bonded to two other carbon atoms, corresponding to the substructure `R-C(=O)-R'`, where R and R' are carbon-containing substituents.
- Count the total number of ketone groups.
- For each ketone group, provide the indices of the carbonyl carbon (C), oxygen (O), and the two carbon atoms (C, C) bonded to the carbonyl carbon.
- Present the results in the following structured format:
  1. Total number of ketone groups: Enclose this integer within <count> and </count>. 
  2. Indices of ketone group atoms: Enclose the list of atom indices for each ketone group within <atom_indices> and </atom_indices>. Each group should be represented as a separate list of four indices. 
- For example, if two ketone groups are found, the output should be formatted as follows:
  1. <count>2</count> 
  2. <atom_indices> [1, 2, 3, 4], [5, 6, 7, 8] </atom_indices>
